Tomcat uses a package renamed commons-logging API implementation which is
hardcoded to use the java.util.logging API. The commons-logging additional
component builds a full fledged package renames commons-logging
implementation which can be used to replace the implementation provided with
Tomcat. See the logging page for usage
instructions.

Tomcat provides factories for JSR 109 which may be used to resolve web
services references. Place the generated catalina-ws.jar as well as
jaxrpc.jar and wsdl4j.jar (or another implementation of JSR 109) in the
Tomcat lib folder.

Users should be aware that wsdl4j.jar is licensed under CPL 1.0 and not the
